Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE I BENJAMIN M.wILLIAms F ORLEANS, LOUISIANA, ASSIGNOR TO RDBERT GAY- nonnINCORPORATED, OF s'r. LOUIS, MISSOURI, A CORPORATION OF MISSOURI CARTONApplication filed January 6, 1932. Serial No. 584,925.

My invention relates to a carton and particularly to a carton formed offiberboard or similar sheet material suitable for shipping and storingcommodities such as cotton goods, yarn, or dry goods, or the like.

The object of my invention is to provide a carton that is simple inconstruction and inexpensive to manufacture and which can readily beassembled even by those unskilled in the art, such as cotton mill andfabricating plant employees.

In the accompanying drawing, whichillustrates one form of carton made inaccordance with my invention, Figure 1 is a horizontal section taken ina plane indicated by the line 11 of Figure 2; Figure 2 is a verticalsection taken in a plane indicated by the line 22 of Figure 1; Figure 3is a plan view of one of the blanks from which the caps are formed;Figure 4 is a plan view of the blank from which the body is formed;Figure 5 is a perspective View showing one end of the carton partiallyclosed; and Figure 6 is a section taken on the line 66 of Figure 2.

The carton may be formed of any bendable sheet material, such as solidfiberboard- Or single or double wall corrugated fiberboard. Forconvenience in illustration I have shown it as made of solid fiberboardbut single walLcorrugated board will usually be employed on account ofits lightness and strength. p

The carton shown comprises a body and two caps, the latter preferablybeing duplicates of each other. from a rectangular blank, shown inFigure 4. This blank is divided by vertical crease lines 1 into sidepanels 2 and end panels 3. Extending parallel with the edges of theblank are crease lines 4, the portions beyond the linesbeing divided byslits 5 into locking side flaps 6 and locking end flaps 7. The body iscompleted by securing the edges of the panels 2 and 3 together by anysuitable means, such as a strip of gummed tape 8 (Figures 1 and 5) toform a tubular structure.

The caps are each formed of a rectangular blank, such as shown in Figure3. This blank is divided by a longitudinal crease line 9 into two parts,one of which is divided by The body is formed 8 vertical crease lines 10into side flanges 11 and end flanges 12. The portion of the blank at theother side of the line 9 is divided by slits 13 into side sealing flaps14 and end sealing flaps 15. A strip of gummed tape 16'secures the endsof the flanges 11 and 12 together to form a tubular structure,

To assemble the carton one of the caps is slipped over one end ofthebody until its crease line 9 lies in the same plane as the crease line 4at that end of the body. The two end sealing flaps are bent Over atright angles, as shown in Figure 5, carrying with them the end lockingflaps 7. The side sealing flaps 14 are now bent over in the same manner,inclosing between themselves and the sealing flaps 15, the locking flaps6, after which the flaps 14 are secured together, as for example, by astrip of gummed tape '17. The carton is now filled and the second capapplied in the same manner. As the looking flaps 6 are held between theupper pair of sealing flaps 14 and the lower pair 15, the cap is firmlyheld in position on the body of the carton by the operation of securingthe edges of the sealing flaps 14 together. As the locking flaps 7 arepositioned below both sets of sealing flaps, they do not directlycontribute to the interlocking of the bod and cap and the device will beoperative i they are omitted. I prefer, however, to include them in thestructureas they not only add strength to the carton but aid insupporting the lower sealing flaps and thus indirectly form a part ofthe interlocking means.

It will be seen that my carton is extremely easy to manufacturerequiring nothing more than the simple operation of slitting andcreasing; that it is readily assembled, even by the unskilled; and thatit constitutes a rigid structure strongly reinforced at the ends,consequently capable of resisting greater shock or pressure than theordinary forms of carton.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. A carton comprising a tubular bod having an inwardly projectinglocking ap, a removable cover provided with an inwardly projecting flappositioned below said locking flap and a sealing flap carried by thecover and extending over the locking flap, whereby the body and coverare locked together by fastening the sealing flap.

A carton comprising a tubular body having a locking flap, and a capincluding a flange portion surrounding one end of the body and sealingflaps between which said locking flap is positioned to secure said bodyand cap together.

3. A carton comprising a tubular body having a pair of oppositelypositioned locking flaps, and a cap including a flange portionsurrounding one end of the body and two pairs of sealing flaps betweenwhich the locking flaps are positioned to secure said body and captogether.

4. A carton comprisinga tubular body having two pairs of locking flaps,and a cap including a flange portion surrounding one end of the body andtwo pairs of sealing flaps, one pair of locking flaps being disposedbelow both pairs of sealing flaps and the other pair of locking flapsbeing disposed between the two pairs of sealing flaps to secure the capand body together.

In testimony whereof, I hereunto aflix my signature, this 31st day ofDecember, 1931.

BENJAMIN M. WILLIAMS.
